Beef rib/roast questions

I have never smoked beef ribs, I've always all of the types of pork ribs and pork butts or shoulders. Are there any differences or procedures when smoking a rack of beef ribs or a beef roast? I am making some pulled pork for my co workers and I am going to try my hand at doing something in the beef catagory to fill up my smoker. I can't see letting smoker space go to waste.
